President Barack Obama took aim at Donald Trump´s contention that he will “make America great again” and the country doesn´t “win anymore.” "America is winning right now. America is great right now," Obama said at a business luncheon in Washington.
Later that day, Obama offered an example of what he thinks makes America great when he addressed 14-year-old Ahmed Mohamed, the Muslim student who was arrested for bringing a homemade clock to school that was mistaken for a possible bomb.
"Cool clock, Ahmed. Want to bring it to the White House? We should inspire more kids like you to like science. It´s what makes America great," he wrote on Twitter.
